Tailor Made options
Define your type of operation
Select the threading method, page C4:
- External or internal threading- Right hand threads or left hand threads- Select the thread type
Select insert size, grade, geometry and type of infeed
Choose your pitch and size of insert. If possible choose a multi-point insert for better productivity.Choose your geometry, grade and type of infeed. Detailed recommendations on page C80.
Select tooling system and type of holder
Choose Coromant Capto or shank tool, depending on clamping possibilities in turret/spindle, on page G5.Choose type of holder and coupling size or shank on page C7.The insert seat must correspond to the size of the insert.
Select suitable shim
Choose correct shim for your pitch/workpiece diameter. See page C45 for CoroThread 266 and page C57 for T-Max U-Lock.Shims are used to give different tilts to the insert and are available in 1° steps from -2° to +4°.Threading holders are supplied as standard with a shim giving a +1° inclination angle.Note: No shims for smaller diameter bars as the angle is fixed at +2°.
Select size, number of passes and speed
The recommendations are intended as starting values. (Page C70)Cutting speed recommendations, see page C82.

Selecting the method of thread cuttingThe machine tool and the design of the workpiece determine which method is to be used to cut a thread. Working towards the chuck is the most common method.
Working away from the chuck is also possible but when producing right hand threads with left hand tools and vice versa, compensation must be made for the negative helix angle by means of changing the shim.
The advantage of using right hand tools for right hand threads and lefthand tools for left hand threads is that the holder design is made to givemaximum suport to the insert.
Note that a holder and insert of the same hand must be used together for the CoroThread and U-Lock programs.

T-Max Twin-Lock® for oil pipe threading THREADING
The T-Max Twin-Lock system
External and internal threading inserts for casing and tubing
T-Max Twin-Lock® is a system that well suits the wide and varying aspects and requirements of the oil related industry, primarily for use in the high volume area of tubing, casing and coupling production.
Tool joint and rotary shouldered connection threads are also covered by the system where the excellent indexing accuracy, edge security and repeatability are ideally suited to modern production units.

Infeed recommendations
The type of infeed, number of passes and size of infeed can have a decisive impact on the threading operation. The infeed recommendations are intended as starting values. Suitable number of passes must be determined by trial and error. The harder the workpiece, the more passes will be required.- The workpiece diameter should not be more than .006 inch (0.14 mm)
larger than the max. diameter of the thread to achieve optimum tool life.
- Infeeds of less than .002 inch (0.05 mm) should be avoided; for austenitic stainless steels, avoid infeeds less than .003 inch (0.08 mm).
- When using grade CB20 the max infeed value should be .003 inch (0.07 mm).
- For C-geometry inserts, spring pass (a pass without infeed) should not be used.
- For Multi-point inserts it is essential that the recommendations on page C79 are used.
- The recommended number of passes for full form inserts can also be used for V-profile inserts.
Cutting speed Starting cutting speed recommendations are given on page C82. Careful observation on the cutting edge can help you to achieve the best possible threading results.- Cutting speed too low - Built-up edge- Cutting speed too high - Plastic deformation of the edge

GC1020 (HC) – N25 (N10-N30)Good all-purpose PVD coated grade with good wear resistance and edge sharpness in non-ferrous materials.H13A (HW) – N25 (N20-N30)Uncoated carbide grade. Combines good abrasive wear resistance and toughness for medium to rough turning of aluminum alloys and brass.
GC1020 (HC) – S20 (S05-S30)A PVD coated carbide grade for toughness demanding super alloy operations. To be used at low cutting speeds.GC1125 (HC) – S20 (S10-S25)PVD-coated carbide grade for toughness demanding super alloy operations. To be used at lower cutting speeds.H13A (HW) – S25 (S20-S30)Uncoated carbide grade. Combines good abrasive wear resistance and toughness for threading of heat resistant alloys and titanium alloys.GC1135 (HC) − S25 (S10-S35)Good all-purpose PVD-coated carbide grade for toughness-demanding super alloy threading. To be used at low cutting speeds. First choice in ISO-S materials.
GC1020 (HC) – H20 (H05-H30)Good all-purpose PVD coated grade with good wear resistance and edge sharpness. To be used at low cutting speed.GC1125 (HC) – H20 (H10-H25)PVD-coated carbide grade. To be used with lower cutting speeds.CB7015 (BN) − H15 (H01-H25)This grade has a low content of cubic boron nitride which makes it suitable for threading applications in hardened steels.
